This invention relates to slat shades, and has for its principal objects to provide circulation of air through the lower portion of the shade while excluding direct glare of the sun and indirect glare from any local niediuni.

Further objects of the invention will becoine apparent from the following specification and the appended drawings, in which Fig. l is a front View of the shade as suspended in an opening;

Fig. 2 is an end view of the shade showing the arrangement of the slats and warp cords; and

F ig. 3 is an end view illustrating a slightly modified form of shade.

The shade is a woven fabric in which slats l0, ll, are the weft, and cords l2 are the warp, and the upper and lower ends are finished by attaching heavy slats 13 and 14C.

rlhe slats l0 in the upper port-ion may be, and preferably are,`of rectangular cross-section, whereby passages 15 for air and direct transmission of light rays are provided between adjacent slats. However, the forni of the slats l0 may be varied to suit individual preference.

The slats 11 in the lower portion each have a il-groove 16 in its lower edge, receiving a tongue 17 on the upper edge of the adjacent slat below. The walls of the groove and the side faces of the tongue overlap so as to provide an indirect air passage and prevent direct transmission of light rays. The grooves 1G are preferably formed by flat faces at an acute angle to the side faces of the slat, and the tongue 17, in the preferred forni, has side faces arranged at a sharper angle than that between the walls of the grooves, as shown in Fig. 2. However, as shown in Fig` 3, the faces of the tongue and groove inay be arranged at the saine angle.

The warp cords indent the edge portions of the slats 1l substantially as illustrated in Figs. 2 and 3.

In both forms the passage between the adjacent slat l1 will correspond to the effective tl'iiclness of the cords l2, and will provide ample passages for the circulation of air.

With a shade of either forni described, the upper portion thereof will permit the transinission ofa desirable quantity of light as well as air, but the lower portionwill intercept all direct light and prevent` any upward reflec-` tion while permitting circulation of It. will bewobvious that these functions of the uppei'and lower portions of theshade are achieved regardless of which surface of the shade is disposed"towardftlie source of light and air. in other words, the shade niaybe reversed without inipairinggthe light and air controlling capacities of its two typesofffslat spaces after the originally outer surface of the shade has become faded or otherwise weathered. ,j l
